Thanks for the suggestion, but that didn't help.

No. CPU usage remains minimal. It takes 45-60 seconds for Mathematica to
start, during which time Activity Monitor frequently shows the process as
"hung". Opening a short, 3-line Mathematica file takes about 20 seconds.
This is on a nearly new system. I don't have slow-downs with any other apps.
